DLCImagePickerController is a fast, beautiful and fun way to filter and capture your photos with OpenGL and your iPhone. The majority of the praise should be directed towards BradLarson for his GPUImage library.
When you clone the repo, you'll need to download GPUImage assets:
git submodule init git submodule update
Here are some examples of the filters that are included. These are being applied to the live camera stream.
or check out on outdoor shoot with the old UI here
It also has a radial blur, that you can move and pinch to your liking on the live view or captured image
Front Facing Camera
There is a front facing camera, however it's still buggy on capture
Apply filters/blur after capture or retake photo
After you capture the image, you can apply new filters and toggle/move/resize the blur as you please or decide to retake it
These images were produced using the sample program included in this repo
